Airbag Light On: Audi A4 Driver Side Water Damage

Hello forum,

'This weekend, I was trying to find the cause of the problem where...'
Water is reaching my rear windshield washer nozzle.

After repeatedly filling the windshield washer fluid reservoir and experiencing constant...
spray. Then I finally found the spot where it stopped.

Specifically, it was a water drainage connection in the driver's footwell.
It is located directly next to the clutch pedal, precisely at that spot.
'and also a bunch of connectors for the wiring harness. They will be used during the process.'
Probably, they all got a little damp (they were well lathered). I then dried the interior.
(mit Aufnehmer und Heizlüfter). So far, so good.

Okay, here's the translation:

Now, 3 questions:

1:
This morning, I started my car and noticed that the airbag warning light is on.
Could it be that one of the connectors is still damp and causing the error? If so, which one out of the approximately 10?

2:
And if I have managed to restore the resistance value of the connector, then...
Does the light turn off automatically, or do I need to take it to a workshop to have the error reset?

3:
'And does it bother the TÜV (German technical inspection agency) if that lamp is on? Because of that, I had to...'
Get the rear windshield wipers working again...

The car is an Audi A4 Avant 1.9 TDI, manufactured in December 1997. The numbers are: zu2: 0588, zu3: 62800G8.

Hello,

1) Sorry, I'm not familiar with that vehicle, but it's possible.

2) For example, the airbag control unit's fault memory must be cleared using VAG-COM.

3) The TÜV (German technical inspection agency) is useless.

Best regards, Rainer.

OK, thanks. I'll check all the connectors again today.
Apply contact spray and let it sit for a few more hours.
Run the space heater.

It's annoying that it doesn't automatically reset after inserting and removing the ignition key. Without a workshop or diagnostic tool, you're really stuck!

Are you sure there isn't some trick to reset that thing?

Which VAG-COM part is the right one for my car?

No, the airbag fault memory does not reset automatically, as it is a safety-critical component.
Without a tester, the light stays on!
Contact spray on airbag contacts? - Well, I'm not sure that's a good idea...

Okay, I sprayed all the electrical connectors in the interior, near the A-pillar, and kept a heater blowing on them for a few hours. I'll also stuff some absorbent cloths under the floor mats tonight and tomorrow morning.

Tomorrow evening, I'll have my trusted mechanic reset it or read the error codes, and hopefully, the warning light will turn off.

Does the fact that the warning light is on mean that the airbag won't deploy in an accident?
So, it's only sharp again after the reset?

Currently, it indicates an error by illuminating the warning light. This means that the control unit has detected a fault. In a serious case, this can lead to impaired functionality (at best) or complete failure (at worst).
"Do you mean reset? Actually, an error code is read and deleted. If this error code doesn't reappear when the ignition is turned back on (meaning the control unit no longer finds any errors during the test), then a function should be restored. Normally."

By the way, if an error is resolved and no longer occurs, the lamp will automatically turn off after approximately 20 ignition cycles (on/off), even though the error code remains stored.
I actually tested that myself once.

I just wanted to leave a comment here.
Okay, so, after the dry sexual activity mentioned above...
I then went to a mechanic and had them reset the error.

The lamp then went out and hasn't turned back on since.
and the TÜV inspection is now also done .
